Accelerometer Plus User Interface Fortify Mobile Products

The KXTF9 tri-axis accelerometer integrates the company’s directional Tap/Double-Tap interface, made possible by an algorithm embedded into the ASIC of the KXTF9 sensor. This feature creates up to 12 unique tap-enabled commands for user-specified functions. The directional Tap/Double-Tap operates via detection of a quick, light tap or double tap on any of the six faces of an object: ±X, ±Y, and ±Z. The algorithm allows the accelerometer to discern a single or double tap and the direction from which the tap originates. With an I2C interface, the KXTF9 features include a user-programmable output data rate with a/d conversions executed at user-defined sampling rates, selectable eight-bit or 12-bit resolutions, user-selectable g-range (2g, 4g, and 8g), and a digital high-pass filter with a user-selectable cut-off frequency.
